Sounds like the other guys were fucking with him...Tyson is definitely a major fucking headcase,but if someone was screwing with him then he was just in going after them IMO.
It's different than that. Tyson gets jumped regularly. That is why he has bodyguards. Every up and coming chump boxer who wants a shot at a title fight uses the same technique when they spot Tyson (or any top boxer out at a bar). They mouth off, call him a pussy, then take a swing at him.
their belief is if they can make a media stink about getting in a scrap with Tyson and knocking him out in a bar fight... they will be handed a 25 million title shot so Tyson can reclaim his honor.
It is stupid thinking... but it happens all the time.
